Length Translator / Visually Impaired Device

Length Translator
Length Translator

This is a Measuring Tape for the Visually Impaired. There is both sound and Braille to help them measure. Length Translator makes a "CLICK" every 10 cm. The Braille numbers on the hub (the yellow part) indicate the remaining length in centimeters. Most parts of the Length Translator can be manufactured by 3D Printing. Those which cannot, such as the winding spring and the bearing, are readily available as they are components of standard specifications. Via open source and Maker culture, We hope these tools can be made available at low cost to those who really need them.
